Abstract
A front image taking device uses a laser scan device to scan an area in front of an automobile to detect an obstacle and a vector representing its displacement over a period of one frame of the scan is obtained by a signal processor. A camera controller predicts from this vector the position of the obstacle at the time of the next frame and sets an image-taking area. A camera obtains a preliminary image of the area and its brightness histogram is obtained by an image processor. The camera controller adjusts the camera according to the histogram such that an image of the area with optimum brightness and contrast is obtained.
